Small update, here are pics of the K200 memory module which adds 64KB of RAM to the onboard 64KB. The module itself has been included in the DMV driver for a long time, the pics are just for completeness' sake.

LN, were you able to read the ROMs of the DMV's harddisk controller I sent you?

Not yet. Have to get a bunch of stuff done for VCFE in a week or so, but after that I should have time.

Thanks to Sandro Ronco for adding the DMV's harddisk controller!
This was the last missing bit to DMV emulation. While experimenting with the new addition, I found that the cursor is wrong, it's a solid block but should be a blinking underscore.

I'm re-acquainting myself with the setup of the harddisks. The partitioning scheme is relatively inflexible (originally 10MB harddisks were used), allowing the CONFIG program to set the number of harddisks and then the number of partitions on those harddisks leading to single 10MB partitions or dual 5 MB partitions per hard disk.
CP/M is not bootable from the harddisk.
There are later DOS utilities that can create a single 20MB harddisk parition per disk but this is incompatible with CP/M partitions.
I'm trying to recreate my old setup that utilised most of a 2x20MB configuration. I'll add a how-to when I have my stuff running again smile

68bit gets credit for adding the WD1000 device that made this possible as well smile

Definitely! It could also find a home in the Kaypro 10 wink
